Hh: mm: SS 到毫秒

Question

我想将时间 (hh:mm:ss) 转换为毫秒。那我该怎么办呢？

例如：时间是：00:00:11

注意：我需要 PHP 代码。

Answer 1

$string = "00:00:11";
$time   = explode(":", $string);

$hour   = $time[0] * 60 * 60 * 1000;
$minute = $time[1] * 60 * 1000;
$sec    = $time[2] * 1000;

$result = $hour + $minute + $sec;

echo $result;
